TELNET to mail user on Exchange 2010
It must be late in the day.
I need help using telnet to connect to a mail client on exchange and send a test message.
I have an application (TigerPaw) on server1 (AD DC FS DHCP) . It needs to send Pop3 to the server Exchange server to gain aynalitics from our mail campains.
That is not working, so thay are requireing me to telnet , connect and send a message to prove the mailserver is allowing pop3 communications.
I set filters in fthe firewalls on both servers with POP wide open (i'll locak it down later).
I can telnet to exchange 110
I cant seem to log in.
what the heck !!!
Can someone help me out.
This is all on our internal lan. could the network firewall be the problem??
Anyway ... please help

please check the settings from a mail client that can connect to the server, it might be possible they use TLS connection to pop3 which would be port 995.
Protocol: POP3
Port (TCP/UDP): 110 (TCP)
Description: Post Office Protocol version 3, enables "standards-based" clients such as Outlook Express or Netscape Communicator to access the e-mail server. As with IMAP4, POP3 runs on top of the IIS Admin Service, and enables client access to the Exchange 2000 information store.
Protocol: POP3/SSL
Port (TCP/UDP): 995 (TCP)
Description: POP3 over SSL. To enable POP3 over SSL, you must install a Computer certificate on the Exchange 2000 server.

maybe thats it. Do i need to open UDP 110 in/out on the servers?
You sure your machine is not blocking the port by chance with windows firewall ? I would also check to make sure the pop3 service is enabled on the exchange box as by defautl ti is now.
Can you telnet to port 25 ?

POP3 is enabled on the Server. I can telnet to 25. I can open a telnet to 110.
I get +OK The MS exchange pop3 service is ready.
If i enter "USER" i get the -ERR command is not valid in this state
